ASA JOHNSON, OF CAIRO, NEW YORK.

IMPROVED MACHINE FOR ROLLING CORNICES.

Specification forming part of Letters Patent No. 18.906, dated December22, 1h57.

To all who/n, it may concern:

Be it known that I, ASA JOHNSON, of Cairo, county of Greene, and Stateof New York,

have invented an Improved Machine for Makings, and to the letters rof,reference marked thereon, in which- Figure l is a plan view, Fig. 2 anend View,

of the machine. Fig. 3 is the reverse end view. Fig. 4 is a side View ofthe saine.

To enable others skilled in the arts to make and use my invention, Iwill proceed to describe its operation and construction.

In the construction of my invention I use any of the known materialsforsuch purposes.

In Fig. 1, A is the crank and crank-shaft; B, the gear-wheel oncrank-shaft; C, the main driving-wheel; I), the gear-wheel on shaft G,which gives motion to allthe uppersetof rollers by means ot' thegear-wheels H, and to the lower set of rollers by means of the lower setof gear-wheels, H'; I, the first upper roller; J, the second roller; K,the third upper roller; L, bevel gear-wheels on a vertical shaft, L', towhich is attached rollers It' and h. IWI is a double bevel gear-wheel onshaft F, and which receives motion from gear-wheel E. N is the guide fordirecting the course of the metal and to assist in forming the cornice;O, the die through which the cornice passes after leaving the rollersand guide; e, screws for attaching said die to inner frame; m', theinner frame; a, the top of the lower rollers appearing through guide N;b, the screws for fastening the caps on the inner frame; a, the caps; c,the set-screw for raising or lowering rollers;

j", screws for fastening the outer to the inner frame; O', the mainbottom plate, to which is firmly attached the inner frame of the wholemachine; t', a portion of the frame or uprights;

j, screws for attaching the same to plate O.

In Fig. 2, A is the crank; C, the drivingwheel; D D, main gear-wheels onshaft G; E, upper gear-wheel on shaft F; K, upper roller; L, horizontalbevel gear-wheels; L', vertical shafts passing through said wheels, andto which aie attached rollers h and h', for pressing the cornicelaterally as it passes through the machine; M', the sides of the innerframe; N, the guide; N', the die; H, the upper gearwheel; H',thelowergear-wheels; a,the1ower roller; J, the shaft passingthrough saidroller; B', the boiler for heating the oil and metal; B2, the furnace;C', the right-and-left screw for fastening outer sides; C, screws forfastening the die to the frame; A', the outer frame.

In Fig. 3, A' is the outer frame; M', theinner frame; G', shaft throughroller I; J, shaft through roller A; H, upper gear-wheel; H', lowergear-wheel; B', boiler; B2, furnace; C', screws for firmly fasteningont-er frames together.

In Fig. 4, H is the upper gear-wheels; I, first roller; J, secondroller; K, thethird roller; L, bevel gear-wheel onshaftL'; M, bevelgearwheel on shalt F in Fig. 1; m, the bearing of shaft F; N, screw forfastening bearing to inner frame; h', roller on vert-ical shaft L'; K K,sliding boxes for the journals g' to work in, and which are adjusted byset-screws c; a, caps on the sliding boxes; I) b, screws for fasteningthe caps to the sliding boxes; G', journals of upper rollers; J,journals of lower rollers; Z, screws for fastening the guide N to themain frame; M', the inner frame; B', the boiler; F', the projection-onthe inside of the plate A', on which the boiler rest-s; G', thescrew-bolts for fastening the outer frames together.

In the operation of my invention I put oil in the boiler B', which is tobe made much longer in the practical machine than in the model.Sufficient length, breadth, and depth, so that the sheets of metal fromwhich the cornice is to be made, may be placed in it under the rollers,and long enough so that the sheets can be drawn back on a carriage andraised up to rollers HAwithout being removed from the boiler, and it isto be made sufficient height to hold oil sufficient to cover the metalas it passes through between the rollers. The oil is heated by means offire being placed in the furnace B2. The machine is then put in motionby turning crank A, which gives motion to the driving-wheel C andgear-wheels E and G, thus putting the whole machine in motion by meansof the other gear-wheels, causing the whole to operate. The sheets ofmetal are then drawn back onto a carriage and placed in contact with therollers H A, and by them drawn in and guided through the machine bymeans of rollers c and,guide N, which serve to keep the metal straightas it passes through between the rollers, and by them is graduallyformed when it passes rollers h and h. Then the 'gutter 'is formed, eachset forming a part, un-

sired, making them male and female, throughV which the cornice ormolding passes, thus forming them into any required corrugated shape.The guide and wheel A form a solid bottom, and pass through the entirelength of the machine, and are of the shape of the rollers and made tocorrespond with them.

o At the discharge end of the guide I form a feinaledie, which itssnugly to the guide N, which is a male die, when the two are made tooperate conjointly. This die gives to the molding or cornice its finish.The roller vI on the first series is differently formed from the rollersJ and K. This is for the purpose of only partially forming the corniceor molding by the rst series of rollers. The rollers J and A are setcloser than the irst set of rollers, and the rollers K and A aresetstill closer, thus causing a gradual forming of the cornice by asuccession of rollers.

I do not confine myself to any number of series of rollers, but will useas many as I may deem necessary to form my cornice gradually. Therollers 71. and h/ on the two vertical shafts L assisted in forming thecornice. The rollers /L holds the metal in its proper position, whileroller 71. forms the gutter. As long as I form any one kind of molding Ido not change the rollers, but use the same rollers, guide, and diesuntil it becomes necessary to form a different-shaped cornice ormolding. Then I-change the roller,guide,and diesvhich is done by liftingout the slides K in boxes k, which are attached by screws to the framesA', where all the rollers can be taken out and another set put in. Therollers are adjusted by means of the set-screws C, which raise or lowerthe rollers by moving the slide K in the box 7c up and down, asrequired. By this arrangement I am able to make cornice and moldings outof metal of all sizes or shapes required, and to make them much cheaperthan they have been made heretofore out of Wood. Y

Having thus fully described the construction and operation of myinvention, what I claim, and desire to secure by Letters Pat-ent, is*

The arrangement of the series ot rollers I a, J a, and K a, guide N, androllers h and h, and die N, for the purpose of forming sheet metal intocorn-ice and gutters for buildings While hot and passing it through themachine in boiling oil, as described, and for the purposes set forth.

ASA JOHNSON.
